Probiotics

Since the discovery of the first antibiotic, penicillin, these medicaments have been our primary weapons in the war against disease. Unfortunately, the overuse of antibiotics has led to the rise of drug-resistant bacteria and, consequently, infections that can be lethal. In addition, antibiotics are useless against viral infections such as HIV infection and hepatitis.

Probiotic, which means "for life", is a general term for microorganisms also known as friendly bacteria, which bolster the body's own defenses against disease. Our bodies are host to several thousand billion friendly bacteria-more than all the cells in your body. These bacteria play a role in digestion and also work in tandem with our immune system to keep us healthy. Among their many jobs, friendly bacteria manufacture some B vitamins, help normalize hormone levels, can help reduce cholesterol levels, and protect against pollutants. They also play a major role in immune function. As we age, we experience a drop in these good bacteria, which makes us more vulnerable to disease. Therefore, it is imperative to restore friendly bacteria back to youthful levels by taking probiotic supplements.

The most beneficial of the friendly bacteria are Bifidobacterium, Lactobacillus acidophilus, and Lactobacillus bulgaricus. One of the most important roles of friendly bacteria is to protect us from overgrowth and infection from fungi and yeasts, which can produce toxic and carcinogenic substances. If left unchecked they may be absorbed into the bloodstream and contribute to other diseases. The most exciting research on good bacteria is their role in supporting the immune system. Bifidobacteria, in particular, have inhibitory effects on pathogens such as Salmonella, Staphylococcus aureus, and Candida albicans. In addition, bifidobacteria also have anti-carcinogenic and tumor suppressing effects.

How do we increase our levels of good bacteria? Eating the right foods can help. A fiber-rich diet can help because intestinal bacteria consume dietary fiber and metabolize it into organic acids that inhibit the growth of bad bacteria. Nonfat or low-fat yogurt made with live, active cultures is another immune- boosting food that is a rich source of friendly bacteria.
